*7.I'm tied up for the moment.
Priscilla: Rich, can you come downstairs for a minute right now?
Richard: I'm sorry I can't. I'm tied up with something urgent at the moment.
Priscilla: Oh, are you on the stupid net again? When are you going to get off?
Richard: Just a minute, Dear! I'm looking at a new jewelry site. I wanna make sure I get the right gift for your birthday, don't I?
Priscilla: Oh? In that case, I'm sorry to bother you. Take as much time as you need.
Richard: No problem.
